BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the technical field of food preservation products, and more particularly to a roll of silicone wrap formed by food-grade silicone with a support layer.

2. Description of the Related Art

In general, food containers or food wraps are used for storing food to maintain the freshness of the food and extend the expiration date of the food.

At present, most food wraps available in the market are made of polyvinyl chloride (PVC) or low-density polyethylene (LDPE). Although these materials are thin and convenient to use, PVC and LDPE may he melted by microwave or heat to release toxics such as plasticizing agent and carcinogenic matter. In addition, a pungent smell may be produced or the food wrap may be to affect the food taste and human health.

Due to the quality of plastic material, available food wraps on market cannot cover food surface when heated to avoid taste change because of heat. This has significantly reduced the functionality of food wraps. In addition, the food wraps available in the market is a disposable product, since plastic products are made of indecomposable materials, so that they must be disposed after use and cannot be recycled or reused, and thus increasing the waste output and affecting the environment seriously. Further, the food wrap is inelastic and has a poor stickiness with the container or food material of other materials, so that the food wrap cannot be wrapped onto the surface of the container or food material easily, and the food wrap is easy to break.

Compared with the food container used for storing food, the food wrap has the following advantages. Although the food container can be used repeatedly, and some containers made of a heat resisting material are microwavable, the food container has a higher price, and users need to spend more money to purchase the food containers, and store food from the original howls or plates. Obviously, the food container is inconvenient and occupies much storage space.

Therefore, the inventor of the present invention provides a natural silicon food wrap in a roll form, wherein the silicone wrap can be used repeatedly and has a high temperature resisting feature.

SUMMARY OF THE INVENTION

To achieve the foregoing objective, the present invention provides a silicone wrap which a very thin silicone layer made of food-grade silicone and attached with a support layer, and wound to form a roll structure, and the silicone wrap has the properties of high elasticity, stickiness and attaching force and can be attached to surfaces of various different apparatuses and food materials, wherein toxics will not be decomposed to jeopardize human health when the food wrap is used for high-temperature heating or freezing. In addition, the silicone wrap is a product that can be used repeatedly instead of one time, so as to reduce the waste output. Even if the silicone wrap is disposed, it can be degenerated or burned to produce silicon powder to reduce the environmental pollution.

To achieve the aforementioned objective, the present invention provides a silicone wrap to be contained in a box having a slide cutter. The silicone wrap comprises: a silicone layer, being a solid silicone blended to a predetermined softness by a blending process, and then rolled to a thickness of 1 cm to 2 cm by a first compression mechanism, and finally pressed by a second compression mechanism to form a sheet structure with a predetermined thickness; and a support layer, which is covered by the silicone layer on a side surface, and then vulcanized, so that molecules of the silicone layer produce a crosslinking effect to improve the flexibility of the silicone layer, and finally route the support layer and the silicone layer which is adhered to the support layer into a rolled structure to improve the flexibility of extending to the needed length and being cut by the slide cutter when used.

Wherein, the predetermined thickness falls within a range of 0.05 mm˜5 mm, and the predetermined softness falls within a range of Shore hardness from A20 to A80. In addition, the heat resisting temperature of the silicone layer falls within a range from −60 degrees to 230 degrees Centigrade to facilitate heating food or freezing and preserving food. Wherein, the support layer is made of halogen-free polyethylene terephthalate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical contents of the present invention will become apparent with the detailed description of preferred embodiments and the illustration of related drawings as follows.

With reference to FIGS. 1 to 5 for a perspective view, a cross-sectional view and schematic views of applications in accordance with a preferred embodiment of the present invention respectively, a silicone wrap 1 is stored in a box 2, and the box 2 has a slide cutter 20, and the silicone wrap 1 comprises a silicone layer 10 and a support layer 11.

The silicone layer 10 is a solid silicone blended to a predetermined softness by a blending process, and then rolled to a thickness of 1 cm to 2 cm by a first compression mechanism, and finally pressed by a second compression mechanism to produce a sheet structure with a predetermined thickness 101. Wherein, the predetermined thickness 101 falls within a range of 0.05 mm-5 mm, and the silicone wrap 1 within the range of the predetermined thickness provides the best wrapping and preservation effects. In addition, the predetermined softness falls within a range of Shore hardness from A20 to A80, and the silicone layer 10 falling within this predetermined softness range has the best extensibility to enhance the effect of using the silicone wrap 1.

It is noteworthy that the raw material for making the silicone layer 10 is food-grade silicone which is harmless to human body, and the silicone layer 10 has a heat resisting temperature range from −60 degrees to 230 degrees Centigrade, so that the silicone layer 10 of the silicone wrap 1 will not be dissolved or damaged while heating food or freezing and preserving food.

The silicone layer 10 covered on a side surface of the support layer 11 and then vulcanized, so that molecules of the silicone layer 10 produce a crosslinking effect to improve the flexibility of the silicone layer 10 and shape the silicone layer 10, and finally route the support layer 11 and the silicone layer 10 which is adhered to the support layer 11 into a rolled structure to improve the flexibility of extending to the needed length and being cut by the slide cutter 20 when used. Wherein, the support layer 11 is made of halogen-free polyethylene terephthalate (PET), and the support layer 11 can be used for preventing the silicone layer 10 from being self-adhered after being rolled.

In FIGS. 3 to 5, during use, the silicone wrap 1 is pulled out from the box 2 to a required length, and then cut by the slide cutter 20, and finally covered onto a desired container 3 or the surface of the food 4, and the support layer 11 is torn away. Since the silicone layer 10 has stickiness due to the properties of its material and can be attached onto a surface of the container 3 or the food 4, and the adhesive force is not affected by liquid. When the silicone wrap 1 is used for sealing the container 3 such a cup having an opening 30, a user simply presses the opening 30 gently to produce a negative pressure to the silicone wrap 1 and the container 3, so as to achieve the effects of sealing the opening 30 and preventing the liquid contained in the container 3 from flowing out. When an irregular shaped food 4 is wrapped, and even if there is water drops on the surface of the food 4 the silicone wrap 1 with its stickiness can be covered onto the surface of the food 4 completely to achieve the effects of isolating air and preserving food.

In the silicone wrap 1 of the present invention, food-grade silicone is selected and used as the raw material for making the silicone layer 10 and PET as the raw material for making the support layer 11. After being processed by various manufacturing processes, the very thin silicone layer 10 is produced and provided for attaching the silicone layer 10 onto the support layer 11 and wound to form a roll structure, and the silicone layer 10 has excellent extensibility, elasticity and stickiness. The silicone wrap 1 will not be dissolved or toxics will not be released during heating or freezing or preserving food, and thus the silicone wrap 1 is harmless to human body. After washing, the silicone wrap 1 can be used repeatedly to achieve the effects of reducing the waste output and protecting our environment. The properties of the material of the silicone layer 10 can be used for attaching substances such as the container 3 made of different materials. In addition, the silicone wrap 1 is covered onto the container 3, and the surface tension is sufficient to support the weight of the container 3, and the container 3 can be stacked for storage to achieve the effect of saving the storage space.

As to a food 4 of an irregular shape, the silicone wrap 1 can achieve the same effect. When the silicone wrap 1 is wrapped onto the food 4, the overlapped portion of the silicone wrap 1 can be self-adhered by electrostatic connection, so as to achieve the effects of isolating air and preserving food. In addition, after the silicone wrap 1 has been used for several times and needs to be disposed, the used silicone wrap 1 can be buried into soil and degenerated, or burned into silicon powder, and thus will not contaminate our environment.
